Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method of manufacturing a claw pole rotor, and more particularly to a novel improvement for easily positioning and overlapping each claw pole rotor via a concave portion and a convex portion.
[0002]
[Prior art]
Conventionally, as a method of manufacturing this type of claw pole rotor, since it is manufactured in-house, a document name or the like indicating the configuration is not disclosed, but as shown in FIG. 9 and FIG. When the second claw pole rotor 2 is overlapped with the one claw pole rotor 1, the pins 3 provided on the first claw pole rotor 1 are used as guides.
[0003]
[Problems to be solved by the invention]
Since the conventional method for manufacturing a claw pole rotor is configured as described above, the following problems exist.
In other words, overlapping using pins means aligning the pin holes. One of the pin holes cannot be visually confirmed, and performing such an operation on a small-diameter claw pole rotor requires a high degree of skill. , A major obstacle to improving productivity.
[0004]
The present invention has been made in order to solve the above problems, and in particular, provides a method of manufacturing a claw pole rotor in which each claw pole rotor is easily positioned and overlapped via a concave portion and a convex portion. The purpose is to do.
[0005]
[Means for Solving the Problems]
The method for manufacturing a claw pole rotor according to the present invention is a method for manufacturing a claw pole rotor in which a plurality of claw pole rotors are concentrically stacked to form a field control rotor. A method of assembling by means of engagement, wherein each of the claw pole rotors comprises first, second, and third claw pole rotors, and the second, This is a method of engaging a convex portion formed on the third claw pole rotor.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, preferred embodiments of a method of manufacturing a claw pole rotor according to the present invention will be described with reference to the drawings. The same parts as those of the conventional example will be described with the same reference numerals.
In the drawing, reference numeral 1 denotes a first claw pole rotor having a substantially plate-shaped cross section. The first claw pole rotor 1 has first and second recesses 10 at a predetermined angular interval. , 11 are formed.
[0007]
What is shown in the cross-sectional views of FIGS. 3 and 4 is a second claw pole rotor 2 for concentrically overlapping the first claw pole rotor 1.
On the periphery of the second claw pole rotor 2, four claws 2a protruding along the axial direction at intervals of 90 degrees are formed, and one claw 2a of each claw 2a has an inward direction. A protruding portion 2A protruding toward is formed.
[0008]
The second claw pole rotor 2 is overlapped as shown in FIG. 5 and FIG. 6 by inserting and engaging the convex portion 2A into the first concave portion 10 to easily perform predetermined positioning engagement. It is performed reliably.
[0009]
Next, what is shown in FIG. 7 and FIG. 8 is a third claw pole rotor 20 which is concentrically superposed on the second claw pole rotor 2 along the axial direction.
The third claw pole rotor 20 is configured such that the projections 20A protruding from the inner surface of one claw 20a among the four claws 20a are inserted into and engaged with the first recess 10 so that each of the claw poles 20 The rotors 1, 2, and 20 are concentrically stacked and superimposed to obtain a known field control rotor of a field control motor.
In addition, although the case where the claw pole rotors 1, 2, and 20 are assembled using the first concave portion 10 of the first claw pole rotor 1 has been described, the assembly can be performed using the second concave portion 11. In addition, it is possible to assemble the case where the concave portion and the convex portion in the above-described embodiment are formed in reverse.
[0010]
【The invention's effect】
Since the method for manufacturing a claw pole rotor according to the present invention is configured as described above, the following effects can be obtained.
That is, it is possible to assemble a plurality of claw pole rotors in a concentric manner by a combination of a concave portion and a convex portion, and assembling is greatly facilitated as compared with a configuration using a conventional pin. Can be made possible.
